用3种瘤株如肝癌腹水型、肉瘤_(180)(S_(180))、艾氏腹水癌(EAC)研究了长白山苦杏仁提取物的抗肿瘤作用。给荷瘤小鼠连续腹腔注射此药600、300mg/kg,灌胃200,100mg/kg10天时,肝癌实体瘤和S_(180)被抑制,其抑癌率为61.7～77.1％。将此药经胃管给小鼠500mg/kg时部分动物死亡,而腹腔注射5g/k巴时,小鼠无死亡。 The anti-tumor effects of extracts from bitter almonds in Changbai Mountain were studied using three tumor lines such as ascites, sarcoma (180) (S_(180)) and Ehrlich ascites carcinoma (EAC). When the tumor-bearing mice were continuously injected intraperitoneally with 600, 300 mg/kg of this drug and 200 or 100 mg/kg was intragastric for 10 days, solid tumors of liver cancer and S_(180) were inhibited, and the tumor suppressing rate was 61.7 to 77.1%. When the drug was given to the mice at 500 mg/kg through the stomach tube, some of the animals died, and when the mice were injected intraperitoneally with 5 g/k bar, the mice did not die.
